ASU School of Geographical Sciences , torrens at geosimulation dot com Background material on the following topics is available on this site: Cellular automata have their foundations in the specification of digital computers. They were pioneered by Alan Turing, John von Neumann, and Stanislaw Ulam, initially as computing media. Later, they have been adopted by other fields outside of computing and put to a wide variety of applications. They have been used in the simulation of urban phenomena with a recent flourish of activity. If you are interested in learning more about cellular automata: their origins and their use in urban geosimulation, you can check out a working paper, entitled, ' How cellular models of urban sytems work ', penned by yours truly. The cell space on which a cellular automaton operates might be considered equivalent in an urban sense to an environment, a landscape, or a territory. The cell space in a cellular automaton is assumed to be both regular in structure, i.e., it resembles a checkered grid like a chess table (although it does not have to be regular), and infinite in extent (infinity is generally achieved by describing the cell space as a torus: its edges 'wrap around' on themselves; again, the cell space does not

A good description is provided here: http://en.wikipedia.org/wiki/Cellular_automata Each bit is mapped to one note in the C-major scale. At every step of the automaton, a chord is played corresponding to bits that are active. Only two rows respond to keypresses: -The buttons on the bottom row allow you to change the current state of the automaton. -The top row represents a binary number corresponding to a Wolfram code ( http://en.wikipedia.org/wiki/Cellular_automata Edit this page or watch for changes using RSS monome, 2007. we are friends, hello.

Extractions: Cellular Automata - The Force of Color Color is to be interpreted as force in these series of experiments. An intensive engine transfomring a planar surface into something other. This experiment is occurs in the space of Red, Green and Blue (RGB). The three values that make up a raster image can be thought of as vectors of force in a 3 dimensional space. This force changes over time according to a set of transformations based on Cellular Automata. This changing force is then applied to a flat plan, deforming it through time and creating a space of colored force. The space of color is a fascinating one and seeing the structures of the images coming through in the interpretation of color as force is an interesting abstract study in the trasnference of information normally seen in one format but now converted into another.
